YFZVFHTR15B Discrete Semiconductor Products

Diodes - Zener - Single

A single Zener diode made up of YFZVFHTR15B is ideal for regulating the voltage of a circuit. It is a specialized type of diode that allows current to flow in either direction through the diode, and is used to protect sensitive components from voltage spikes or transients caused by unexpected occurrences. The Zener diode is used in applications that require voltage regulation, such as power supplies and electrical surge protection circuits.

Application Field:

The YFZVFHTR15B Zener diode can be used in a variety of applications, including:

• Regulating the voltage of a circuit;
• Protecting sensitive components from voltage surges or transients;
• Inverter/power supply circuits;
• Overvoltage protection;
• Ground fault protection;
• Current regulation; and
• Backup power systems.

These diodes can also be used in a range of other applications such as battery charging, signal conditioning, DC-DC converters, switching regulator assemblies, and data transmission systems.

Working Principle:

The YFZVFHTR15B Zener diode is a two-terminal device that functions according to the well-known Zener breakdown effect. When a high potential is applied to the diode, it breaks down and begins to conduct current. The current-voltage (I-V) characteristic of the diode is heavily dependent on the reverse-bias voltage applied to it.

When forward bias is applied to the diode, it behaves like a regular diode, allowing current to flow in one direction only. When reverse bias is applied, electrons and holes form an active region in the diode. If a voltage greater than the Zener voltage is applied, the electrons and holes are accelerated, which increases local electric fields. As a result, a large number of electron-hole pairs are created and the device breaks down, allowing a large current to flow through it.

The Zener voltage of the YFZVFHTR15B is designed to break down at a specific voltage, allowing it to act as a voltage regulator. It is capable of handling currents of up to 1.5A and can withstand voltages of 15V under normal operating conditions. The diode can be used to regulate voltages up to 18V, though this may cause damage to the device.

The YFZVFHTR15B Zener diode can be used in a variety of applications, from voltage regulation to protecting sensitive components from voltage transients. Its robust design and low power consumption make it an ideal choice for a wide range of applications.
